HAME-FASTEN ER.

SPECIFICATION forming part of Letters Patent N o. 553,012, dated January 14, 1896.

Application filed .August 2l, 1895. Serial No. 560,016. (No model.)

To LZ-.Z whom t may concern:

Be it known that I, JOEL ALEXANDER MC- CAWLY, a citizen of the United States, residing at Canton, in the county of Trigg and State of `Kentucky, have invented a new and useful Haine-Fastener, of which the following is a specification. p

This invention relates to haine or collar fastenere of the class which embody oppositely disposed snap-hooks whose Shanks have interlocking teeth on their opposing faces, and which are secured together in the located position by holding the interlocking teeth together by means of a looking contrivance.

The purpose of the present invention is to improve this class of fastenings and provide against the accidental displacement of the parts when the device is in service, and to provide a 'fastening which will be simple and compact, and which can be relied upon to give satisfactory results.

Other objects are contemplated and will be apparent in the subjoined description, and the improvement will be more particularly set forth hereinafter and claimed, and is shown in the annexed drawings, in whichw Figure 1 is a perspective view of a hamefastener constructed in accordance with this invention. Fig. 2 is aside elevation showing the relative disposition of the parts when the Shanks of the snap-hooks are released, the obverse cheek being broken away so as to disclose the iiattened side of the rotary lookingpin. Figs. 3 and et are detail views showing different positions of the rotary looking-pin and its operating-loyer. Fig. 5 is a detail view of the rotary looking-pin and its operating-lever disassociated from the snap-hooks.

Like numerals of reference designate Acorresponding parts in all the gures of the drawings.

The snap-hooks 1 and 2 are of similar construction, and are supplied on their opposing or meeting faces with interlocking teeth 3, by means of which the said snap-hooks are held positively in the loca-ted position. One of the snap-hooks, as 1, is provided with cheeks 4 entending in parallel relation, and between which the shank portion of the snaphook 2 operates when relatively adjusting the snaphooks to effect the proper fastening of the haine or collar to which the device may be applied. These cheeks also serve to guide the snap-hooks in their movements and provide bearings for the rotary locking-pin and have 5 5 openings which are in transverse alignment for this purpose.

The rotary lockingpin 5 is journaled at its ends in the opening formed in the cheeks 4 and one side is iiattened or out away for a dis- 6o vtance corresponding to the distance between the inner sides of the teeth, so that when the locking-pin is rotated in its bearings to bring the flattened side opposite to the adjacent shank portion of the snap-hook 2 the latter 65 vcan be moved so as to disengage its lockingteeth from the corresponding locking-teeth of the snap-hook l, thereby admitting of the proper adjustment of the snap-hooks the one upon the other. After the snap-hooks have 7o been adjusted or properly positioned and the interlocking teeth 3 are brought together the locking-pin 5 is rotated on its bearings so as to move the iattened side 6 thereof away from the shank portion of the snap-hook i', thereby 7 5 holding the said interlocking teeth 3 in positive engagement. To facilitate the turning of the rotary locking-pin the latter is provided at one end with an operating-lever '7 which is formed at its outer end with a lateral exten- 8o sion 8, by means of which the said operatinglever can be gripped by the fingers when it is required to aotuate the same to secure or release the snap-hooks. The operatingdever 7 is constructed and disposed so as to bear 8 5 against the contiguous edge of the adjacent snap-hook with sufcient friction, so as to hold it in the position shown in Figs. 1 and 3, and it is so arranged with relation to the ro tary locking-pin thatin the event ot' it assum- 9o ing a pendent position, as shown in Fig. 4, the flattened side G of the rotarylocking-pin will not face or come opposite to the shank ofthe snap-hook 2 and admit of a disengagement of the interlocking teeth 8. To effect the latter 9 5 result it is imperative that the operating-lever 7 loe moved from the position shown in Figs.

1 and 3 to that shown in Fig. 2, which is dia met-rically opposite to that occupied by the said operatingdever when the latter is in a roo normal position-when the snap-hooks are interloeked. One end of the rotary lookin g-pin is headed and its opposite end is upset or riveted so as to secure the operating-lever thereon, and the cheeks Li are located between the said operating-lever 7 and the head 9 of the rotary locking-pin 5, and by means of which the latter is held in its bearing.

Vhen in service the sn ap-hooks are engaged with the ends of the collar or the llame to be secured together, and to fasten the said parts the shank portions of the snap -hook are brought together to the required adjusted position and the interlocking teeth 3 are held in positive enga-gement by turning the rotary locking-pin so as to move its flattened side 6 away from the adjacent side of the contiguous shank portion of the opposing snap-hook.

Vhen it is required to release the snap-hook the rotarylocking-pin is turn ed so as to bring its flattened side directly opposite and facing the shank portions of the snap-hooks, when the latter can be moved the one upon the other, or disengaged, as required.

XVhat I claim is- The herein shown and described llame or collar fastener comprising oppositely disposed snap hooks which are adapted to have their shank portions move the one upon the other and provided with interlocking teeth on their opposing or meeting faces, one of the snap hooks having cheeks between which operates 3 space formed between the said cheeks whereby when the said flattened side is caused to face the shank portions of the snap hook the latter can be moved by a quick adjustment, and when the said flat-tened side is moved away from the shank portions of the snap hook the interlocking teeth of the shank portions thereof will be brought together and held in positive engagement, and an operating lever applied to one end of the rotary locking pin to turn it in its bearings, and adapted to bear laterally against the edge of the contiguous snap hook, and hold the locking pin against turning substantially as set forth7 for the purpose described,

In testimony that I claim the foregoing as j my own I have hereto affixed my signature in the presence of two witnesses.
